For the fourth year in a row, this festival on Governors Island celebrates the sights and sounds of Brooklyn. In addition to a fun music lineup—Lez Zeppelin (that’s not a typo—it’s Lez Zeppelin, not Led) and Shinobi Ninja headlined last year—the event also promotes local artists and vendors through Boardwalk Arts and Albee Market, and donates a portion of ticket sales to NYC’s Center Against Domestic Violence.
